75B light-ish primer strikes

[Kaibab270]

I have a 1996 75B military import that I've had probably 13 years now. Last weekend I noticed my primer strikes were noticeably lighter than my other 9mms. Honestly not sure how long it's been doing it. About a year ago I replaced all springs in the gun. All factory springs except +2lbs (I believe) on the mainspring. Shouldn't that have made it better? I hardly ever dry fire it so I dont think the firing pin is peening. It does still go bang everytime so I'm not terribly worried about it but I would like the strikes to be a little better for any hard primers I might come by. Anybody else seen this or have this happen?

 If the gun is firing on the first strike every time you have no issue. What exactly makes you think the strikes are light?
Far more info is needed here.

I know, I stated it hasn't caused issue and I'm not loosing sleep over it, I just would prefer it to leave more stout strikes. I made the opinion by comparing it to my other 6 pistols. I'll see if I can dig out a piece of brass from it for a picture but it's about half the depth of all my other handguns of various manufacturers. It is especially odd to me considering the mainspring is slightly stronger than factory weight.

Have you checked how far the pin protrudes from the breach face?

have you removed the firing pin recently and cleaned the channel?

[Kaibab270]

I have not, (not) surprised I didn't think of that. For all I know it's been doing it for over a decade. I just started keeping my brass recently otherwise I'd never notice. The primers have rounded dents in them so I dont think its damaged but I'll have to look at that. Thanks.

I removed the firing pin and replaced the spring with a factory unit about a year ago. Pin looked fine then. Cant remember if I cleaned the channel out or not but I'd imagine I did. Can still check though.

I'd ensure that the firing pin is not chipped or damaged and that all related springs are in good condition. Barring a timing issue I don't think you have a problem.
Comparing what fired cases look like especially if they are from different brands really isn't any way to tell if you have an issue or not. Many variables come in to play here since each brand will leave it's own unique impressions on a fired case and case pressure has a tremendous affect on how spent primers can look.

This.  If you changed ammo, changed load data, or just changed primers, spent brass will vary in appearance. I only see a deep round dimple on the lightest of loads. More serious stuff tends to iron out the primer a bit reducing the appearance of the pin strike.  9mm being higher pressure round, dont expect the same appearance as a .45

I understand that CGW sells an extended firing pin.  You might give them a call.

Were you using Privi Partizan ammo?  They are notorious for hard primers.  I have had many misfires with that ammo.  When it happens I pull the trigger again and it fires the second time.  PPU also makes the 9mm "Monarch" brand ammo that Academy sports sells.  You will see PPU on the headstamp.

Quick update for those interested. I've chalked it up to hard CCI primers. I used Federal today and primer strikes are solid.
